1、双层壳体结构，外壳承受入口压力，进出口位于同一水平线上，可作为多级管道泵或去掉外壳作为槽罐泵使用。
With two-casing structure, the outer casing bears inlet pressure. Inlet and outlet are at same level. It can be used as multi-stage pipeline pump or groove pump by removing the casing.
2、 首级叶轮为吸入式叶轮，提高抗汽蚀性能；特殊工况，可设计加装诱导轮，以降低汽蚀余量。
First-stage impeller is suction one, which enhances anti-cavitation performance. Under special working conditions, inducer can be designed and installed to reduce NPSH.
3、 加大轴承箱储油室，带有独立循环的自动润滑系统；轴承部件集成化设计，拆卸组装方便。
With oil chamber with enlarged bearing casing and independent and cyclic automatic lubrication system. With integrated design of bearing parts, it is convenient in dismantling and assembling.
4、采用平衡盘装置平衡轴向力，残余轴向力由配对的向心推力球轴承承受。
Balance axial force with balance disk. The residual axial force is undertaken by paired radial-thrust ball bearing.
5、 选用增强型刚性轴，整体无接点；下部配置流体动力滑动轴承，线速小、磨损轻，减少运转振动。
Select enhanced rigid shaft, it’s overall contactless. Fluid dynamic sliding bearing is configured below
with low line speed, slight wear and reduction in revolving vibration.
6、采用便拆型电机支架，带加长段膜片联轴器，不必拆卸电机即可进行轴承
部件、密封部件和平衡装置的维修更换。
With convenient-to-dismantle TV support and diaphragm coupler with lengthened segment, it is
not necessary to dismantle motor to repair and replace bearing and sealing parts and balancing device.
7、 管口按API标准三倍载荷设计，确保运转安全、稳定、可靠。
Pipe orifice is designed according to API standard twofold load. API standard chassis is adopted
to ensure safe, stable and reliable operation.
8、按API682标准密封腔设计，采用集装式机械密封，便于安装和维修，
轴向压缩量不受任何连接件轴向尺寸影响，无需调整。
Packaging-type mechanical seal is adopted according to seal design of API682 standard. It is conve
-nient in installation and maintenance. The axial compression is free of influences of axial dimensions of
any connecting pieces. It is not necessary to make adjustment.
